I wrecked my Archangel stock...what now?

Spray the screw with Pam or wipe with a paste wax, fill the hole with epoxy, insert the screw ...let dry and unscrew the screw, works everytime.
If you can find an epoxy, with carbon in it, it would be stronger. If you have a boat repair/supply company near by, it would be a great place to find the supplies you need and maybe a little help with your problem.

Good to know. You could also fill the hole with epoxy, let it dry and drill & tap it.
 
Helicoils and other od/id threaded inserts are great for metal on metal repairs. For polymer stocks a simple two part epoxy repair will hold up just fine as long as you allow a full cure. You can even match the stock colour with pigment that won't compromise the mixture.
 
Clean out the old hole, then fill it with a two part epoxy, let it cure then drill a new hole. The screw should be able to tap I easily enough.
 
Apparently loctite.has a new product out to repair stripped threads. I'm suppose to get some to try at work in a few months and it's apparently good to fix head bolts with.

Acklands has a Loctite thread repair kit on their website. Is this the same one you're talking about?
 
Google "slimsert " we us them at work all the time when the threads get stripped out of magnesium cases. It is same idea as a heli-coil just 5 times the product. If it works on a 3000 hp turbine engine I'm sure it will work on a rifle stock.

25-30 inch pounds once fully cured. Since you are fitting your Mosin with this particular stock I'm assuming you are going for accuracy gains, so I would just adjust the torque on the screws after checking your groups.
 
Fixed!

All fixed! I used the Loctite Stripped Thread Repair kit and a 1/4-20 cap screw.

I tried using the epoxy method but I couldn't get it to work. As soon as the epoxy cured and I tried putting the original screw back in, the screw would just tear the new threads out. I tried filling the hole with epoxy, and drilling and tapping a new hole, same results. I then got the Loctite kit and used the original screw, it worked a little better but the threads still tore out. So, after using a drill to clean out the epoxy I then thought about using a common screw, 1/4-20. The hole was oversized anyway. So I narrowed the head on the cap screw so it would sit below flush on the rear tang. I then used the kit one last time and let it cure. Once cured I removed the screw and the results I had were successful. I put the screw back in and tightened it and the threads didn't strip out and I got a tight fit to the stock. I took my Mosin to the range this morning and it worked like a charm! To me it seemed like the epoxy couldn't get enough contact with the threads to produce a good enough thread profile. When I switched to 1/4-20 the threads are bigger so there was more contact for the epoxy to conform to.

Thanks everyone for your help and advice.

Ok, the easiest and best solution is to use Acraglas from Brownells, stock bedding compound. It is a two-part epoxy, but has a proper release agent specifically for the purpose.
It has been used for years to rebuild threads and is the next best thing to helicoils. It's $20 and available at almost all gunstores.

Helicoil.

This, absolutely the best way to replace damaged threads. Ive used these on cylinder heads before and if they hold there im sure a action screw will pose no issues.

EDIT. didn't read rest of responses first, usually you can get helicoils in any thread size easily(at least from suppliers here in Vancouver) OP glad you got it sorted out!
